I have a collection of Japanese gyutos and a few customs. If you want a usable knife with a decent grind then stick with a Vic.
VIctorinox. Used in and approved for use in commercial kitchens. Thin blade. Won Cooks Illustated's recent chefs knives competition over many other far more expensive Japanese and European competitors.
You can Google the review from people/pro chefs who cut more in a week at work than you probably will in a lifetime.
